We look at the division of 801891 by 25 
We're looking to find how many times 25 goes into 801891.

Advancing to step 1:
The number 25 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 25

Going ahead to step 2:
If we divide 80 by 25, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 5 after subtracting 75 from 80.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 25

On to step 3:
The number 25 fits into 51 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
If we subtract 50 from 51, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 25

Step 4:
If we divide 18 by 25, we get 0 and a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 320.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 25

Step 5:
When dividing 189 by 25, we get 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 3207.0
Subtracting 175 from 189 leaves us with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 25

Moving on to step 6:
25 can be fit into 141 5 times, resulting in a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 32075.0
Subtract 125 from 141 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
If we divide 160 by 25, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 32075.6
If we subtract 150 from 160, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
25 can be fit into 100 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 32075.64
Subtracting 100 from 100 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 32075.64
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
0 divided by 25 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 32075.64
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 32075.64 with a remaining 0.0.
